GENETICS REVIEW
A physical trait that shows as a result of an organism’s particular
genotype.
PHENOTYPE
An organism that has two different alleles
for a trait.
HETEROZYGOUS
The mathematical chance that an event
will occur.
PROBABILITY
Form of a trait that appears to
overshadow or mask another form of the
same trait.
DOMINANT
A synonym for heterozygous.
HYBRID
A characteristic of an organism controlled by
a gene.
TRAIT
Male sex cell.
SPERM
Strands of DNA and protein found in the
nucleus of a cell carrying the code for the characteristics of
an organism.
CHROMOSOME
A synonym for homozygous.
PUREBRED
A tool for predicting possible traits in
offspring.
PUNNETT SQUARE
Occurrence of a trait that makes individuals
different from members of the same
species.
VARIATION
Form of a trait that can disappear in a population but can reappear in future
generations.
RECESSIVE
Segment of DNA on a chromosome
controlling the inheritance of traits.
GENE
Female sex cell.
EGG
The different forms a gene may have for a
trait.
ALLELE
An organism that has two identical alleles
for a trait.
HOMOZYGOUS
The genetic makeup of an organism for a trait; alleles in a gene pair.
GENOTYPE
Pair of chromosomes containing alleles for
the same traits.
HOMOLOGOUS
The passing of traits from parent to
offspring.
HEREDITY
* Knowing the vocabulary is half the battle . . . You must also know how to
apply the terminology in order to answer
questions about the relationship between
parents and their offspring.
